MOTOR-DRIVER' IYINIURING DEVICE.

Application filed January 27, y1923. Serial No. 615,221.

' To all whom t may/concern.'

Be it known that I, GEORGE WV. Moonn, a citizen of the United States,and a resident of theCity of Chicago, county of Cook, and State ofIllinois, have invented certain new| and useful Improvements inMotor-Driven Manicuring Devices, of which the following isaspecification.

kThis invention relates to motor driven manicuring devices and. has forits object the provision of a device of this character which is adaptedto bevdetachably connected to and driven by a suitable motor, togetherwith' means for detachably mounting manicuring tools of various kinds insaid device.

Other objects willappear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and. claimed. f v

The invention will bebest understood by reference to the accompanyingdrawings forming a part of this specilication, and in which, 1 A

Fig. 7, is a view partlyfin section of the rotatable member of thedevice, showing the means for connecting the shaft and the manicuringtools,

Fig. 8, is a view partly in section on the line 8er-8 of Fig. 7

Fig. 9, is a section on the line 9-,9 of

the end of the Fig. 8, and

Fig. 10, is an enlarged detail view of one form of a manicuring toolVused in connection with the device.

4Referring to the drawings, 10 represents 11 the shaft connectedtherewith, and 12 the manicuring instrument adapted tobe driven by theshaft 11. The housing 10is provided Vwith a rotatable member '13, whichhas its forwardend mounted in the bearing 14,

there being a collar 15 mounted on the member for centeringthe same.Adapted to be seated on shoulders 16 providedin the housing 10 is athimble 17 surrounding themember `13 and having its forward end abuttingagainst the collar 15 as shown in Fig. 3. Seated in the thimble 17 is abushing 13` which surrounds the member 13. The bushing 18 may be of anysuitable material, and is preferably provided with longitudinal slits19, and the slit portions are provided with an annular constriction 20as ,shown in Fig. 4. A cap 21 is disposed about the bushing 1S and isadapted to be threaded into the housing 10, the spun ends 21 of said capwhen in position serving to secure the bushing 18, the thimble 17 andconsequently the rotatable member 13 by reason ofthe engagement ofthethimble 17 with the collar 15. The rear end of the member 13 isprovided with a slot 22 as shown in Fig. 7, and adapted tobe slidablyVdisposed in said slot is a key 23 upon the end of the flexible shaft11. The flexible shaft 11 is preferably provided with an outer casing orsheath 24 in the ordinary manner, an to the sheath 24 adjacent the endof the shaftv 11 there is connected a plug 25, such plug being providedwith a groove 26 adjacent its end. By this arrangement when the key 23on the shaft 11 Vis placed in the-slot'22, the plug 25 is telescopicallyengaged with `the bushing 18, the action being lsuch that Jcheconstricted portion 2O of the bushing is expanded by the end of the plug25, continued movement of Vthe plug inwardly, causing the constrictedportions to snap into the groove 26 thus detachably securing the plug tothe housing and thereby retaining the end of the shaft 11 in properposition,v to drive the member 13. Y

The forward portion of the` rotatable member 13 is preferably providedwith a cylindrical bore for the reception of `almanicuring tool of thetype shown in the various figures. In order to detachably retain amanicuring tool in operative position in the member 13, Ipreferablycprovide such member with a transverse slot or opening 27, as

shown in Figs. `2, 3, 7, 8 'and 9, which slot longitudinal portions 28,the ends of-which are secured on the opposite sides of the member 13,there being a transverse portion 29 traversing the slot 27. Themanicuring tool 12 preferably has its inner end bevelled as shown at 30,and also is prefer-l ably provided with a notch 3l. The man-V curingtool l2 as shown is provided with a head 32 which may be in the form ofan emery wheel, abrush, buffer, iile or the like, as is necessary inmanicuring operations. lVhen it is desired to place the inanicuring toolin position in the rotatable member, the bevelled end 30 is pushedinwardly beneath the portion 29 ot the spring, causing such portion tosnap into the notch 3l, thereby holding the manicuring tool againstrotation with respect to the member 13, and also against casualdetachment, such manicuring tool being extracted by applying some littletension thereon which causes. the portion 29 to raise out ot the groove31.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without depart ing from the spirit of theinvention. I, therefore, do not wish to be limited` tothe precisedetails of'construction set forth, but desire to avail myself of suchvariations and modifications as come within the sccpe of the appendedclaims.
